You could always result to an unofficial IRC channel, instead of a live chat.
Do you know how many of these kids know how to use mIRC, or another IRC? and, not to use as a file transfer.
BTW live chat and hundreds on, does not work. They would need moderators for the moderators and rules to be followed. Like don't ask for free things, no swearing, one person at a time, blah blah blah. mIRC and IRC channels have some nice controls to control much of the chat, but there are so many idiot kids, and adults, that would just be so annoying that the IRC would become a failure in less than a month.
